To all whom it may concern.

Be it known that I, FRANK J. Marousrmx,

a citizen of the United States of America,-

' for aeroplanes and has particular reference to inflatable gas bags associated with the aeroplane wiigs and fuselage, the gas bags assistin the otation of the aeroplane durin flig t thereof.

ith the above general objectsl in. view and others that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of'parts hereinafter more fully described, shownn the accompanyin drawings and claimed.

In the rawings, wherein like reference characters designate corresponding parts throughout the several views, f

Figure 1 is a top plan view of an aeroplane constructed'in accordance with the present. invention showing the gas bags associated with the aeroplane wings and fusela e,

Fi re 2 is across sectional view ta en on l--II of Fig. 1 showing 'the manner of securing one of the gas -bags to the aeroplane wing,

Figure '3 is a fragmentaryl longitudinal sectional view taken on line Ill-III of Fig. 1, I

igure 4 is a cross sectional view similar to Fig. 2 of a modified form of the invention showing the gas bag completely enclosing the aeroplane wing, and

Fi re 5 is a detail sectional view takenA on line -V of Fig. 4.

Referrin more in detail to the accompanying rawing there is illustrated an aeroplane embodying a fuselage 1 provided with a forwardly positioned motor driven propeller 2, rear vanes 3 and a steering rudder-4, the fuselage 1 having oppositely directed planes 5.

The planes designated by the numeral 5 may be Hat as shown in the preferred form of my invention or they may be formed in any other desired shape suitable' to act as a mount and shape retaining means for the 1niatable .gas ba The general wing contour may be varie somewhatL by changing the 'planes and fusela 'the invention 'are s own more' clearly in Figs.

desi of the planes 5 but the princi al use of t ese planes is to act as supports or the inflatable gas bags.

and maybe varied as 'desired b alte the form of the bags. y ung I The wing contour proper is formed by the inflatable gas bags.

The inflatable gas bags aociated with the in the preferred form of 1 to 3,.tb.e gas bagincluding-a bottom wall 6 extending beneath the lower face ofthe plane 5 with side walls 7 extending up'- wardly and overlappingthe upper edges of the planewhile an end wall 8 overla s the outer end of the plane. The 'upturne sides and .ends of the bag have channel guides for receiving the edges of the plane and carry screw receiving attachinglugs 9 as clearlyl illustrated for anchoring the bag to the plane 5. A valve 10 is associated with each bag for supplying a gas thereto While spacing cords 11 imit the expansive movement ofthe bag relative to the plane. The inner vendsof the bag adjacent the fuselage 1 are secured' thereto by attaching tabs 12.

A similar gas bag i's secured to the fuselage 1 intermediate the planes 5 and empennage 3, the bag 13 being positioned beneath the fusela e, extending above the same and being attac ed thereto as at 14, a filling valve being, associated with the bag 13 similar to the valve for the plane, bags 6. The gas bags associated with the lane and fusela may be inflated as desire and will assist 1n the flotation of. the aeroplane during flight.

A modified form of bag is shown in Figs.

4 and'5 wherein the ba -walls 15 enclosing' a central pocket forme of spaced walls 16 integral -with the outer walls 15 and within which pocket the plane 5 of the wing is received, the bag, being slidably mounted upon the pla'ne from the outer end theret and anchored thereto in any suitable manner, movement limiting cords 17 connecting the ba walls 15 and the pocket walls 16. e gas ba may be constructed of any suitable material such as silk or rubber, and in one form of the invention the ba are positioned beneath the planes while in the otherA form of the invention the bags coinpletely enclose the planes, 'the main idea' in connection with the device beilig the provision of inflatable gas bags being associated with the planes and fuselage of an aeroplane. y

spirit and sco p I What is claimed as new is :f- "ne:

' 1: In an aeroplane having'honzo While there arel herein shown. andfdescribed -the preferred embodiments of the present invention,A understood that minor changes may be made therein without departing from thethereof.

ntally eli-v tending planes, inflatable gas bags surround ing said planes, a filling valve carried'by each bag; and spacing cords provided in Y said bags for limiting the expansion of the same.

2. In an aeroplane having horizontally extending planes, inflatable gas bags surround-V ing said planes to'aord proper wing contour, a filling valve carried by each bag, and Aspacing cords provided' in 'said bags for limiting the expansion'of the same.

20 A3. In an aeroplane having horizontally eicit is nevertheless to bebags bem sldably. mounted provided in said bags ture.'

inflatable gas bags having ockets formed therein, the said gas upon the said a filling valve and spacing cords 'protendin planes,. centra planes 4m secured i thereto, carricd'by each ba v vided in said bags orlimitxng the expansion of the same.

4. In an aero lane having horizontally extending planes', inflatable vbags secured to `sai planes, the said ags -v comprising FRANK J. MATQUSHEK.
